电梯门套选材，别听销售忽悠，先搞清楚自己的真实需求。不锈钢和大理石，各有各的主场。

Elevator door frame material selection, don't listen to sales scams, first understand your real needs. Stainless steel and marble each have their own home court.

不锈钢门套：务实耐用的“经济适用男”

Stainless steel door frame: a practical and durable "economical and suitable for men"

优势是性价比高——包一个电梯门套造价通常只要几千块；防撞耐造，搬运家具磕碰后轻微抛光就能修复；防水防潮，不怕地下室返潮发霉。304不锈钢含镍量≥8%，耐腐蚀性优于201或430材质；厚度方面，家用常用0.8mm-1.0mm，商用及高人流场所建议1.2mm-1.5mm。

The advantage is high cost-effectiveness - the cost of packing an elevator door frame is usually only a few thousand yuan; Durable and collision resistant, furniture can be repaired with a slight polishing after being bumped during transportation; Waterproof and moisture-proof, not afraid of basement moisture and mold. 304 stainless steel has a nickel content of ≥ 8% and better corrosion resistance than 201 or 430 materials; In terms of thickness, the commonly used thickness for household use is 0.8mm-1.0mm, while the recommended thickness for commercial and high-altitude flow fields is 1.2mm-1.5mm.

缺点是质感偏“工业风”，镜面款容易留指纹。如果选不锈钢，建议选黑钛或古铜色拉丝面，比银色更显出彩，且抗指纹性能更好。

The disadvantage is that the texture tends to be "industrial style", and the mirror style is prone to leaving fingerprints. If stainless steel is chosen, it is recommended to choose black titanium or antique copper salad silk surface, which looks more advanced than silver and has better anti fingerprint performance.

大理石门套：气场全开的“贵公子”

Marble door frame: the 'nobleman' with a fully open aura

优势是天然纹理少见，质感厚重显档次，可与地面石材统一形成空间延伸感。缺点是造价昂贵（材料+加工+安装动辄上万）、脆性大搬运时易崩边、颜色偏冷与原木风/日式风难搭配。

The advantage is that the natural texture is unique, the texture is thick and classy, and it can be unified with the ground stone to form a sense of spatial extension. The disadvantages are expensive cost (materials+processing+installation often cost tens of thousands), high brittleness, easy edge breakage during transportation, cold color, and difficulty in matching with wooden/Japanese style wind.

选型建议：对号入座，不纠结

Selection suggestion: Take the right seat and don't hesitate

预算3000以内：果断选304不锈钢（黑钛或古铜色），不要考虑大理石

Budget under 3000: Choose 304 stainless steel (black titanium or bronze) decisively, do not consider marble

预算8000以上且风格为轻奢/新中式：大理石值得投入

Budget over 8000 and style of light luxury/new Chinese style: Marble is worth investing in

折中方案：金属仿石纹门套（不锈钢表面热转印大理石纹理），价格居中、不怕磕碰

Compromise solution: Metal imitation stone pattern door frame (stainless steel surface heat transfer marble texture), priced in the middle and not afraid of collision

提醒：电梯门套底部非常容易受潮和被撞击。不锈钢要把底口收边做严密；大理石底部建议加厚处理

Reminder: The bottom of the elevator door frame is most susceptible to moisture and impact. Stainless steel should have the bottom edge tightly closed; Suggest thickening the bottom of the marble
